Meclazine is another option that works well. My husband uses it on occasion and it does not make him tired.

I normally do not get seasick, but the Pacific Ocean in a small boat can be a "memorable" experience....I used a Scopalamine patch when we hit rough water and it was too late for anything to stay down. The instructions say to put it on 4 hours before going out, but we still had an 11 hour day ahead of us, so I slapped it behind my ear. Sure enough, in 4 hours, I stopped barfing. I slept the rest of the way, and didn't mind at all being comatose.

(By the way, I'd started out with one of those electrical relief bands that shocks your wrist so your fingers contract every 3 or 4 seconds. It was the first thing I threw overboard when I started throwing up.)

Try whatever first to see if it makes you tired.

WOW! So many responses! Thank you everyone. I have done the horizon deep breathing thing during to near hits. Once going to Block Island and the other returning from Lanai - both about 1hr...if it was longer I don't think deep anything would have kept me from hucking. I don't know which ferry I'll take, but the cat is such good advice KEH. Will check the surf conditions the night before and then time it if necessary. Again mucho mahalos to everyone!!!

I'm not sure where the Sea bands are worn but they probably are stimulating an acupuncture point. You can find the point yourself. It works for seasickness and morning sickness. Just above your watchband, with your palm facing up, find the bone on the thumb side of your lower arm. On the inside aspect of that bone there is a point that if you press it will cause some tingling and numbness in your hand. Gently pressing it will help dispel any quesiness.
